circuit. Output current is muted when the chip tempera-
ture exceeds 175_C (typically).
(2)
below 0.5V, the output current will be muted. Pin 7 should
be pulled up above 2.0V during normal use.
(3)
1.4V (typically). Make sure it stays above 1.6V during
normal use.

age. In each case, only the drivers are muted. During
muting, the output pins remain at the internal bias volt-
age, roughly (V

GND also serves to prevent oscillation of the IC, so select
one with good temperature characteristics.
